Abstract

Gaia DR3 photometry data have revealed new resolved binary systems in the Orion Nebula Cluster (ONC). The previously compiled list of ONC stars [1] in the region of the sky where free-floating planet and stars with planetary systems were discovered using the James Webb Telescope (JWST) was used. The technique of searching for binary stars in the Gaia DR3 catalog [5] was applied. The results allowed us to refine the number of binary stars in the central part of the ONC.
